> I think you misinterpreted some of the statements I made, Daniel. For instance, the "parabolic" condition B^2=A*C>0 does not imply the xy points have to be either the xaxis or yaxis; it could be any straight line through the origin, depending on the values of A, B, and C. Also, having all points in a solution lie along a single straight line through the origin does not imply that the parabolic condition must hold; it might be one of the lines of a "hyperbolic" (B^2>A*C) set.

It does not look to me a standard technique to study a bunch of conic hypersurface in statistics. Usually people just study the eigen values and eigen vectors of the covariance matrix. This is much simpler, and it tells a lot of thing as wellposedness, observability, impact of the data error etc...
